Abstract: Provided is a mutant UDG having improved thermal sensitivity compared to a wild-type UDG. The mutant UDG of the presently claimed subject matter having a high thermal sensitivity has no inhibitory effect on the PCR reaction and thus can be advantageously used for the development of PCR/qPCR Premix and particularly PCR diagnostic kits employing UDG which requires the use of relatively low temperature in melting and amplification steps.

Abstract: The present invention relates to a method of recycling C-14 in a spent resin, the method includes: i) heating a spent resin raw material including 14CO2 in the presence of moisture by microwave irradiation; ii) refluxing, by condensation, water vapor in a first processing gas produced by the microwave irradiation and released from the spent resin raw material; and iii) removing water vapor from the first processing gas by the refluxing, and transporting a second processing gas including 14CO2, which is released from the spent resin raw material, to the outside, and to an apparatus for recycling the same.

Abstract: The present disclosure provides a device and method of generating a nonlinear waveform signal dissipating low power and operating at a high speed. The device includes: a digital preprocessing unit configured to quantize an effective input signal to generate a linear data signal and a residual signal that is a difference between the effective input signal and the linear data signal; a nonlinear digital-to-analog conversion circuit (DAC) having a nonlinear relationship between an input and an output and configured to convert the linear data signal into a first analog signal; a linear interpolation DAC configured to convert the residual signal into a second analog signal to enable a generation of a converted analog signal by an addition of the second analog signal to the first analog signal; and an output circuit configured to output the converted analog signal as a nonlinear waveform signal.
